(hereinafter, the “Concessionaire”), Tax ID (RUT) No. [***], with registered address at [***], represented in this act by Messrs. Diego Arrasa (National ID No. [***]) and Martín Radesca (National ID No. [***]), in their capacity as attorneys-in-fact, who agree to the following extension and amendment of the Comprehensive Management Agreement (hereinafter, the “Amendment”).

FIRST: Background

1) On February 6, 2003, the MDN and the Concessionaire entered into the “Comprehensive Management Agreement” pursuant to Articles 21 to 23 of Law No. 17,555, dated September 18, 2002, and Decree No. 376/002, dated September 28, 2002, as amended and supplemented, the purpose of which is the administration, exploitation, operation, construction and maintenance of the Carrasco International Airport “Brig. Gral. Cesáreo L. Berisso” (SUMU) (hereinafter, the “AIC”), for a term of twenty (20) years as from the Taking of Possession by the Concessionaire, which took place on November 21, 2003.

II) By Resolution of the Executive Branch No. 284/005, dated February 25, 2005, the amendment of the Comprehensive Management Agreement was authorized with respect to the extension of runway 06-24 to 3,200 meters, the extension of the deadline for the construction of Taxiway B in parallel, as well as the relocation of the Cargo Terminal.

III) By Decree No. 229/014, dated August 6, 2014, the term of the Comprehensive Management Agreement was extended until November 20, 2033, establishing the obligation of the Concessionaire to make additional investments.

IV) By Law No. 19,925, dated December 18, 2020 (“Law 19,925”), the National System of International Airports (“SINAI”) was created, and it was declared that the operation of airport services is a priority objective for the development of the country.

V) By Law 19,925, the Executive Branch was empowered to designate the airports that would comprise SINAI. By Decree No. 108/021, dated April 9, 2021 (“SINAI Decree”), the Executive Branch established that the airports comprising the SINAI would be the AIC, the “Laguna del Sauce International Airport ‘CIC Carlos A. Curbelo’” (SULS), the Rivera International Airport “Pte. Gral. (PAM) Oscar D. Gestido” (SURV), the Salto International Airport “Nueva Hespérides” (SUSO), the Carmelo International Airport “Balneario Zagarzazú” (SUCM), the Durazno International Airport “Santa Bernardina” (SUDU), the Melo International Airport (SUMO) and the Paysandú International Airport “Brig. Gral. (Av.) Tydeo Larre Borges” (SUPU), without prejudice to the authority of the Executive Branch to include other airports in the SINAI when circumstances so justify.

VI) With the exception of AIC and SULS, the remaining airports currently included in the SINAI are administered, operated and maintained by the National Directorate of Civil Aviation and Aeronautical Infrastructure (“DINACIA”).

VII) The Interior Airports (as defined below) require economic investments to be adapted in order to comply with the international certification standards required by the applicable regulations (Latin American Aeronautical Regulation “LAR 139”), especially the methods and recommended practices of the International Civil Aviation Organization incorporated into domestic law.

VIII) In view of the foregoing, the Concessionaire proposed to the MDN to assume responsibility for providing the services necessary for the implementation of the SINAI and to make investments in the amount of USD 67,000,000, thereby extending the scope and term of the Comprehensive Management Agreement for such purposes.

IX) The committees formed within the Ministry of Economy and Finance and the MDN issued favorable opinions regarding the proposal submitted by the Concessionaire, considering that its acceptance would allow for the adequate fulfillment of the purposes pursued by Law 19,925, particularly the strengthening and modernization of airport facilities and infrastructure, through the incorporation of technology and the improvement of safety conditions and operational efficiency, in accordance with the minimum requirements set forth in Article 3 of said Law and the certification standards required by Article 4 thereof pursuant to the applicable regulations (LAR 139).

X) Based on the foregoing and on the provisions of the second paragraph of Article 2 of Law 19,925, by Resolution of the Executive Branch No. 218/021, dated November 5, 2021 (hereinafter, the “Resolution”), this Amendment to the Comprehensive Management Agreement was approved, establishing as consideration an investment of USD 67,000,000 in the airports of the SINAI (except for AIC and SULS).

XI) On October 6, 2021, the Concessionaire obtained the consents and amendments required under the publicly offered negotiable obligations issued by the Concessionaire in 2007, in order to consent to this Amendment. On October 22, 2021, an affiliate of the Concessionaire obtained the consents required under its bond due in 2032 necessary to consent to this Amendment.

FOURTH: Guarantees

4.1. The Concessionaire shall provide a performance bond in the amount of USD 7,608,000 (seven million six hundred eight thousand United States dollars), which shall expressly establish that it guarantees the obligations of the Concessionaire vis-à-vis the MDN in relation to the AIC and the Interior Airports, and which shall remain in force and valid until the total extinction of each and every obligation of the Concessionaire under the Comprehensive Management Agreement and this Amendment. For such purposes, the Concessionaire may opt to provide such guarantee through one or more bank guarantees, surety insurance policies and/or cash, within a period not to exceed ninety (90) days as from the execution of this Amendment, failing which the provisions of Section 5.1.1, subsection 13, of the “Comprehensive Management Regime” of the Comprehensive Management Agreement shall apply.

None of the Parties shall be deemed to be in breach of its obligations relating to the execution of the Investment Schedule and/or the Investment Programs when such breach is caused by a Force Majeure Event. In such case, the affected party (the “Affected Party”) shall notify the occurrence of a Force Majeure Event to the other party, detailing the impact on the normal performance of the obligations relating to the execution of the Investment Schedule and/or the Investment Programs, and shall have a period equal to the time elapsed due to the Force Majeure Event, up to a maximum of ninety (90) consecutive days as from the occurrence of such Force Majeure Event, to remedy the situation (the “Cure Period”).

If, after the Cure Period has elapsed, the Force Majeure Event persists or it is not possible to remedy the situation, the parties shall, during a period of sixty (60) consecutive days following the expiration of the Cure Period, negotiate in good faith the amendments to the affected Investment Schedule and/or Investment Program, which may include extending the applicable deadlines, substituting the affected work(s) or investment(s) with substitute work(s), or another mutually agreed solution, provided that such amendment complies with the provisions of Clause Second of this Amendment and Law 19,925, and always taking into consideration the Investment Amount. If no agreement is reached within such period, neither party shall be entitled to rescind or terminate the concession, and the Comprehensive Management Agreement and this Amendment shall remain valid and in force in all their terms, and the Parties may resort to technical arbitration for the purpose of resolving the remediation of the affected Investment Program and the Investment Schedule, as applicable, in accordance with Section 4.15 of the “Comprehensive Management Regime” of the Comprehensive Management Agreement.

8.2. In the event that there are delays in the execution of the Investment Programs and/or the Investment Schedule caused by delays in expropriations or the completion of urgent possession procedures that may be necessary in accordance with the provisions of Clause Thirteenth, the mechanism set forth in this Clause Eighth shall apply.

NINTH: Buyback by the MDN

The MDN, with the approval of the Executive Branch, may proceed: (i) with the buyback of the management of the AIC and the Interior Airports, which must necessarily be carried out jointly (“Total Buyback”), or (ii) with the buyback of the management of one or more of the Interior Airports (“Partial Buyback”). In any of the foregoing cases, the buyback shall proceed when there are duly justified public interest reasons that render it necessary or convenient, and, in the case of Total Buyback, subject to fair compensation to the Concessionaire, in accordance with the provisions set forth below.

9.1. In the event of a Total Buyback, the following shall be reimbursed to the Concessionaire: (i) the value of all investments in construction, works and/or repair of real property carried out at the AIC in accordance with the relevant investment programs approved by the MDN, net of accumulated depreciation as of the end of the fiscal year in which the buyback occurs. For such purposes, in the case of construction, works and/or repairs, the useful life considered shall be the period from completion thereof until the expiration of the concession term;

​

​

(ENGLISH TRANSLATION – For informational purposes only)

(ii) a proportional part of the amount paid at the auction of the shares for the first twenty (20) years of the concession, calculated in accordance with the following formula:

K × [1 − (1 / (1 + i))ⁿ] = I

where:

I = amount to be reimbursed

n = years of the Comprehensive Management Agreement elapsed at the time of the buyback, with 20 being the maximum number

i = LIBOR rate plus fifty (50) basis points

K = P × i / [1 − (1 / (1 + i))²⁰]

where:

P = total price paid for the shares of the corporation

i = LIBOR rate plus fifty (50) basis points

(iii) a proportional part of the cash amount paid by the Concessionaire as consideration for the extension of the concession term by ten (10) years starting in 2023, calculated in accordance with the following formula:

K × [1 − (1 / (1 + i))ⁿ] = I

where:

I = amount to be reimbursed

n = years of the Comprehensive Management Agreement and this Amendment elapsed at the time of the buyback, counted as from the ten (10)-year extension of the concession term

i = LIBOR rate plus fifty (50) basis points

K = P × i / [1 − (1 / (1 + i))¹⁰]

where:

P = cash price paid as consideration for the ten (10)-year extension

i = LIBOR rate plus fifty (50) basis points

(iv) the value of all investments made at the Interior Airports in accordance with the Investment Programs up to the end of the month in which the buyback occurs, which shall be duly identified in the Financial Statements or supported by a report issued by an independent professional, updated pursuant to the formula established in Section 4.13 of the “Comprehensive Management Regime” of the Comprehensive Management Agreement, as amended, defining α with a value of zero and β with a value of one. With respect to item (iv), as from the fiscal year beginning January 1, 2034, accumulated depreciation as of the end of the fiscal year in which the buyback occurs shall be deducted from the updated value. For such purposes, the useful life shall be the period between fiscal year 2034 and the expiration of the concession in 2053, applying the straight-line depreciation method;

(v) the accumulated value of expenses incurred for any purpose (net of operating income of the Interior Airports), directly used to maintain, operate and preserve the Interior Airports from the execution of this Amendment through December 31, 2033 inclusive, duly identified in the Concessionaire’s Financial Statements or supported by a report issued by an independent professional, updated as of the end of the fiscal year in which the buyback occurs pursuant to the formula set forth in Section 4.13 of the “Comprehensive Management Regime” of the Comprehensive Management Agreement, as amended, defining α with a value of one and β with a value of zero. As from the fiscal year beginning January 1, 2034, the value referred to in the preceding paragraph corresponding to expenses incurred through December 31, 2033 shall be reduced by an accumulated annual rate of five percent (5%) until the end of the fiscal year in which the buyback occurs. It is agreed that only in the event of a Total Buyback occurring as from

​

​

(ENGLISH TRANSLATION – For informational purposes only)

the fiscal year beginning January 1, 2034, there shall be no compensations or reimbursements between the parties nor any payments with respect to expenses incurred (net of operating income of the Interior Airports) directly used to maintain, operate and preserve the Interior Airports as from the fiscal year beginning January 1, 2034.

9.2. In the event of a Partial Buyback, it is agreed that there shall be no compensations or reimbursements between the parties nor any payments of any nature whatsoever, unless the AIC is subsequently bought back and, therefore, Interior Airports must necessarily be bought back, in which case the provisions of Clause 9.1 shall apply. If, at the time of a Partial Buyback, there are investments provided for in the Investment Programs pending execution with respect to the Interior Airport(s) subject to such Partial Buyback, works of equivalent value shall be carried out at one or more of the remaining airports under the Concessionaire’s management, subject to the prior approval of the Executive Branch and always taking into consideration that the Investment Amount shall not be exceeded.

9.3. In the event of a Total Buyback, the performance bond shall also be returned to the Concessionaire.

9.4. In the event of a Total Buyback, the contracts entered into by the Concessionaire that are necessary for the comprehensive management of the AIC and the Interior Airports shall be transferred to the MDN at no cost thereto, and in the event of a Partial Buyback, only those contracts entered into by the Concessionaire that are necessary for the comprehensive management of the relevant Interior Airport shall be transferred.

9.5. For purposes of this Clause, “LIBOR” means the London Interbank Offered Rate offered in the London Interbank Market for deposits in United States dollars, published by Intercontinental Exchange Benchmark Administration Ltd. and disclosed on the Bloomberg terminal screen, page BBAM1, or any successor page, at 11:00 a.m. (London time) on the date of determination. In the event of a permanent cessation of LIBOR for a given LIBOR tenor (for example, one-month LIBOR or one-year LIBOR), but LIBOR continues to exist for other tenors, LIBOR for the desired calculation period shall be determined by linear interpolation between (i) the LIBOR rate for the longer tenor that continues to exist and is shorter than the desired calculation period, and (ii) the LIBOR rate for the shorter tenor that continues to exist and exceeds the desired calculation period. If interpolation is not possible or there is a permanent cessation of LIBOR for all tenors, the parties shall select a replacement rate (which may be SOFR or SOFR plus a margin plus fifty (50) basis points), adjusted with an additional margin if necessary to reflect the difference in yield or risk between LIBOR and the replacement rate (the “Margin”), plus fifty (50) basis points. The selected replacement rate shall be the variable rate prevailing in credit markets at the time as the successor to LIBOR. If such replacement rate is below zero, it shall be deemed to be zero (without prejudice to adding the Margin, if applicable, plus fifty (50) basis points in all cases). If no clear prevailing rate exists, the parties shall mutually agree on a rate or apply an index customarily used by banks in Montevideo, Uruguay, as a replacement for LIBOR, plus the applicable Margin, plus fifty (50) basis points.

9.6. Consequently, the parties agree to render Section 5.1.3 of the “Comprehensive Management Regime” of the Comprehensive Management Agreement null and void.

TENTH: Environmental Authorizations

If it becomes necessary for the Concessionaire to obtain a Prior Environmental Authorization for the execution of certain works provided for in the Investment Programs, the reasonable costs of processing such authorization shall be charged to the Investment Amount, and the MDN shall provide its cooperation in obtaining such authorization. It is hereby stated that, depending on the investment contemplated in the Investment Programs, a Prior Environmental Authorization may not be required for works to be carried out at the Interior Airports pursuant to Article 2 of Chapter

​

​

Such Investment Programs shall detail annual groups of works and their corresponding investment guarantees for purposes of Clause Fourth. Consequently, the parties agree that the “Master Plan,” “Annex A – Technical Bases,” and any other annex, document, Communication, Inquiries, Responses, and clauses of the Comprehensive Management Agreement and its “Comprehensive Management Regime” referring to investments or works and their respective commissioning, operation and maintenance at the AIC shall not apply to the Interior Airports.

12.2. In the event that no agreement is reached within such period, this shall not prevent partial agreements from being reached with respect to one or more of the Interior Airports, and the lack of agreement shall not entitle the parties to rescind or terminate the concession, the Comprehensive Management Agreement and this Amendment remaining valid and in force in all their terms, and an additional period of thirty (30) consecutive days being opened to reach an agreement. If no agreement is reached within such additional period, the provisions determined by the MDN shall apply, which shall act in good faith, in accordance with the following guidelines: determining the investments and works necessary to comply with the Certification standards of each Interior Airport in accordance with the minimum requirements established by Article 3 of Law 19,925 and the respective Codes (which include, among others, investments in runway, taxiway and apron pavement, visual lighting aids, apron lighting, refurbishment of passenger terminals, equipment for control by the National Air Police and perimeter fencing, firefighting and rescue equipment), based on the Investment Schedule, all in accordance with Clause Second of this

​

​

(ENGLISH TRANSLATION – For informational purposes only)

Amendment and Law 19,925, always taking into consideration that the Investment Amount shall not be exceeded by the Concessionaire.

12.3. Without prejudice to the foregoing, if once the Investment Programs have been determined, the investments provided for to comply with the Certification standards of the Interior Airports in accordance with the minimum requirements established by Article 3 of Law 19,925 and the respective Codes result, in their entirety, in an amount lower than the Investment Amount, the MDN shall be entitled to request the Concessionaire to amend the Investment Programs to include additional investments, provided that the amendments proposed by the MDN do not modify the investments and works already determined in the Investment Programs that are necessary to comply with the Certification standards and comply with Clause Second of this Amendment and Law 19,925, subject to the cap of the Investment Amount.

12.4. For purposes of evidencing the amount of investments made, the Concessionaire shall submit to the Control Unit a report issued by itself or by an independent professional regarding the groups of works of each Investment Program at the time of executing the provisional acceptance record and, if applicable, at the time of executing the final acceptance record, in accordance with Clause Fourth.

THIRTEENTH: Taking of Possession

13.1. The Concessionaire shall implement the Investment Programs at each Interior Airport, and therefore apply the amounts provided for in the Investment Schedule, as from the respective taking of possession, as defined herein, except in the case of the Initial SUDU Investment, which shall commence in accordance with Clause Fourteenth.

In the event that the Prior Environmental Authorization is required only for certain investment(s) or work(s), the processing thereof shall not prevent the taking of possession, it being understood that the commencement of the period

​

​
